Hybrid Two-stage and Double-effect Lithium Bromide Refrigeration-heat Pump Compound Cycle
In CCHP system, The waste heat quantity emitted from lithium bromide absorption refrigeration is large and low grade, so it is difficult to use directly. This paper proposes a hybrid two-stage and double-effect Lithium Bromide refrigeration - heat pump compound cycle. In this cycle, the condenser co...

| description | In CCHP system, The waste heat quantity emitted from lithium bromide absorption refrigeration is large and low grade, so it is difficult to use directly. This paper proposes a hybrid two-stage and double-effect Lithium Bromide refrigeration - heat pump compound cycle. In this cycle, the condenser could emit higher temperature heat, which could increase the utilization rate of emitted waste heat. The cycle’s heat source is the back pressure steam, and it can take advantage of the low-grade thermal energy emitted from the refrigeration process to heat up the boiler make-up water. This paper takes existing double-effect lithium bromide absorption refrigeration and the single effect lithium bromide heat pump as contrast, the refrigeration - heat pump compound cycle system omits an evaporator and a condenser, which could decrease the temperature difference in heat exchange. And the energy analysis and the exergy analysis show that the compound cycle can improve exergy efficiency and energy utilization efficiency. |
